I have 2 Gigabyte G1 GTX 1080 in my system. One of them wasn't giving the audio output of HDMI so I decided to update its BIOS. However, after the update, the performance of the card has taken a significant hit. The performance isn't even 1/5th of the original. valley benchmark which used to run at 100ish FPS was running at 20 FPS avg. I checked the hardware stats using GPU-Z and found out that the card's bandwidth is very low compared to my other 1080 and memory type (GDDR5X) is not being detected. Any solution?

Here are the screenshots of both my 1080s in GPU-Z:

P.S. I forgot to make a backup when updating BIOS.
